On his lead segment, Dr. Oz said high-protein, Paleo-inspired diets accelerate weight loss and prevent heart disease and diabetes.

“One in three of you are not getting enough protein,” said Dr. Oz. “It’s the single best thing to fight disease and lose weight fast. It’ll jump-start your metabolism, and you’ll actually lose more weight with the calories from protein.”

Dr. Oz ripped recent reports claiming a high-protein diet is as bad as chain-smoking for causing early death, heart disease, and cancer.

If anything, Dr. Oz said consuming high-quality animal protein such as grass-fed beef, poultry, wild fish, and pastured eggs (all recommended on the Paleo diet) is good for you.

He said a 20-year study confirmed that a high-protein diet reduces heart disease and diabetes, especially for people in their 30s and 40s.

Dr. Oz suggested eating five to six servings of protein each day, and said each meal should always contain protein (whether from animal sources, nuts or plants).

Fitness expert Mark Sisson said people who go Paleo will notice health changes almost immediately, including weight loss, improved sleep, and more energy. Sisson told Palm Springs Life the Paleo diet enhances weight loss by turning your body into a fat-burning machine.

“Over time, you become good at burning off your own body fat for energy rather than depending on carbohydrates throughout the day,” said Sisson, author of The Primal Blueprint. “It takes about 21 days for your body to switch to this mode of fat-burning, and that’s when you’ll really start to see results.”

A recent study published in the European Journal of Clinical Nutrition indicates the Paleo diet is twice as effective as other diets for promoting weight loss and reducing belly fat.

“Clinical trials have shown the Paleo diet is the optimum diet that can lower the risk of cardiovascular disease, blood pressure, markers of inflammation, help with weight loss, reduce acne, promote optimum health and athletic performance,” said Dr. Loren Cordain, author of The Paleo Diet for Athletes and The Paleo Diet Cookbook.
